IMPROVEMENT IN ENDLESS-TREAD HORSE-POWER LINKS.

Specification forming part of Letters Patent No. 202,054, dated April2,1878; application filed December 30, 1876. 1

To all whom it may concern:

Be it known that I, WILLIAM SAMSON, of Berkshire,in the county ofFranklin and State of Vermont, have invented a new and valuableImprovement in the Mode of Securing Horse- Power Links; and do herebydeclare that the following is a full and clear description of theconstruction and operation of the same, reference being had to theannexed drawings, making a part of this specification, and to theletters and figures marked thereon.

in the bed of the link, and out on the lag far enough to. be therefirmly secured by means of a screw.

A represents the staple which is used for securing the corrugated orcrimped link 0 to thetread. This staple is made of steel or iron,

and the ends are both bent inward in the same direct-ion,and one madelonger than the other. The shorter end is made sharp, so as to be driveninto the tread, either above'or below the mortise, as shown in- Fig. 2,while the longer end is so shaped as to allow the two bands to passunder it, as shown in Fig. 1, and has the screw or bolt B passed through.it. This staple passes through the depression D in the corrugatedtread-iron, and thus rigidly secures the iron to the tread at its centerin such a manner that the iron cannot work loose.

In order to prevent the link 0 from elongating, a bolt, rivet, or screwis passed through it at each crimp or corrugation, as shown at 1 2 3 4 56.

In order to form a sufficiently strong backing for this iron, to preventall elongation, the

tenon O has a strap, of band or wrought iron or other suitable material,G, passed entirely around it from the corner at F, and the end E is madeto form a lap, as shown. The two ends are securely fastened together byarivet, G, or other fastening, and thus a mortise is formed that isindependent of the link, and which is secured in position by the samerivets or bolts, 1 2 3 4. 5 6, that hold the cogs. This lap E comes upover the corner, and prevents the mortise being worn away at this pointby the calks of the horses shoes, when the tread or lag becomes worn,and thus enables the 1. The mortise G, formed of iron, and serv-.

ing as a backing in securing the corrugated link (3 to the tread or lag,substantially as shown.

2. The mortise G, having the lap E as means for protecting the corner,substantially as described,

3. The corrugated or crimped link 0 having a rivet passed through it ateach bend or depression, substantially as set forth, so as to preventelongation.

4.. The mortise G, having the ends united by the rivet G, which rivetenters the tenon in a direction vertical to the strain.

combination with the link 0 whereby the WILLIAM SAMSON.
